Answer: 71%
Explanation:
The Budgeted material loading charge was 84% of material cost of $1,268,000.
Yet the actual loading cost was $164,840 which means that actual loading cost percentage is:
= 164,840 / 1,268,000 * 100%
= 13%
Profit margin = Budgeted percentage - Actual percentage
= 84% - 13%
= 71%
